There was a guy who was very keen at telling jokes. One day at a meeting he told one and everybody laughed except a man.
He told another and everybody laughed again except the man. And that continued until the 9th joke.
He noticed the man, and told one nonsense joke. At that time, everybody stayed quiet except the man who laughed energetically.
He asked the man then, “You`re very strange man. I`ve told nine funny jokes and you`ve not had any reaction, and when I told one nonsense one, you found it funny”.
The man replied : “I`ve just understood the first one”
